Gravity, relativity, theoretical physics, particles, quantum, black holes and more... Both "basic" and "advanced" explanations. Exploring the source site is highly recommended.

Invictus, check out this clip, which links to ap iece suggesting that physicists are becoming disenchanted with string theory.

Thanks Josh, I know that controversy. Science, especially theoretical physics (like climatology, geology, anthropology and genetics) became the battlefield of "rival" groups since the last quarter of the 20th century. I'm just trying to follow the thesis and counter-thesis, arguments and discussions, hearing what different scholars think on the subject. I clipped this site, because it harbors lots of interesting materials.

For me, even the existence of a force called "the gravity" is really debatable
